I've had the same problem. The problem I can identify, the answer/solution I cannot.

you may open multiple windows and multiple tabs altogether (2 or 3 still ok), Try the limit with 1 page at a time.

Also do not open multiple forums on multiple windows. Might confuse the...whatever, if you persist will only lead you to a page "database corrupted something..something" (blank screen).

I think it has to do with simultaneously recognizing who's online or not.

Basically, the page will not finish reloading, especially the ads.

I assume it needs extensive work to fix this, which may jeopardize the forum itself, including the tips & tricks already uploaded.

I'll leave the explanation & solution to the experts.

But still this forum is much much much ( have I said enough much?)better than the others, the information is faster than light, the communication works both ways, the information is laid on the table (try other forum, you'll be going on circles), the community have soul within the discussion. Anyway that's just me talking.
